Method and system for recognizing images

An image recognizing system, recognizing at least one testing image according to a plurality of classes, wherein each of the classes comprises a plurality of sample images, the image recognizing system comprising:

• an image capturing unit, capturing the at least one testing image;
• an image recognizing unit, coupled to the image capturing unit;
• and
• a classifier training unit, coupled to the image capturing unit and the image recognizing unit;
• wherein the classifier training unit generates an average image of each of the classes according to the sample images;
• wherein the classifier training unit generates a feature enhancement mask according to differences between the average images of the classes,
• wherein the classifier training unit enhances the sample images of each of the classes by using the feature enhancement mask to generate a plurality of enhanced sample images corresponding to the class,
• wherein the classifier training unit trains a classifier according to the enhanced sample images corresponding to each of the classes,
• wherein the image recognizing unit enhances the at least one testing image by using the feature enhancement mask to generate at least one enhanced testing image,
• wherein the image recognizing unit classifies the at least one enhanced testing image into one of the classes by using the classifier;
• wherein the image recognizing unit recognizes that the at least one testing image which is belonged to the one of the classes.
